Abstract (en)
[origin: EP1376918A1] An optical switch controlled by remote power electric circuit, switches between main and reserve optical paths. The power is supplied through an additional optical signal along the main path, at a wavelength lying outside the wavelength range used for useful optical signal transmission. A wavelength optical coupler connected to a photodiode and main path, extracts the additional optical signal.
